Combined machining system and method of ultrasonic vibration assisted grinding and magnetic polishing

InactiveCN109623504ARealize online automatic sharpeningImprove removal efficiencyWorking fluidMachined surface
The invention relates to a combined machining system and method of ultrasonic vibration assisted grinding and magnetic polishing. Ultrasonic vibration enables a diamond grinding wheel or workpiece toperform forced reciprocating vibration to enable suspended abrasive particles in working fluid to erode a machined surface and sharpen the surface of the grinding wheel. When the grinding wheel is outof the contact with the workpiece due to vibration and magnetorheological fluid flows through a gap between the grinding wheel and the workpiece, a magnetorheological effect occurs due to being subjected to the action of magnetic field force, an ''elastic polishing film'' is formed by rapid solidification, and hard abrasive particles contained in the magnetic fluid are evenly distributed on the surface of the ''elastic polishing film'', so that finishing process of the workpiece and sharpening of the grinding wheel are achieved. When regaining to be in contact with the workpiece due to vibration, the grinding wheel is directly involved in grinding the surface of the workpiece, and the forced reciprocating vibration of the grinding wheel enables frequent pulse cutting action to exist between the grinding wheel and the workpiece. According to the combined machining system and method of ultrasonic vibration assisted grinding and magnetic polishing, three technologies including ultrasonicmachining, grinding machining and magneto-fluid polishing are multi-combined, automatic on-line sharpening of the grinding wheel is realized, and high material removal rate and low damage surface quality are obtained.

Distributed GNSS space division ciphering communication method

A distributed GNSS space division ciphering communication method is suitable for floor distributed communicating system based on GNSS, which is principally characterized in that before the data sending terminal DTE transmits the data, the self located communication zone according to the latitude and longitude information provided by the GNSS signals, and the cipher key corresponding to the zone is selected to cipher the transmission data. Because the zone cipher key has fixed length, the ciphering adopts a block cipher system. The sending terminal and receiving terminal DTE have a same region cipher key comparison table simultaneously, the receiving terminal DTE can search the region cipher key comparison table to obtain the decipher cipher key by recognizing the region number on the cipher text head section added by the sending terminal, and then uses the cipher key to decipher the cipher text and acquire the plaintext. The communication cipher key in the method dynamically changes with the variation of the located region of the sending terminal, which has free communication region partitioning dimension assisted with enrich and various encryption algorithms, thereby greatly improving ciphering flexibility, decoding-proof performance and tamper-proof performance.
